Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
PLANTS, PEOPLE, PLANET, EarlyView.Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

PWO proteins are associated with PRC2 since their emergence in vascular plants
New Phytologist, Volume 250, Issue 6, Page 4002-4021, June 2026.Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...
